The Impact

In this paper the impact toughness of the basalt fabric reinforced epoxy resin composites was discussed. In the test, the basalt fabricwas used to reinforce the TDE-86epoxy resin, and 70#anhydride was used as curing agent. The mode of [45°/-45°] was chosen to layering and prepare the unit-cells. Resin Transfer Molding instrument was used to cure and make the basalt fabricreinforced epoxy resin composites, and the instron-based Dynatup9250HV material impact testing machine was used to test the impact resistance. Conclusion: in the low-velocity impact test, the maximum load the sample can bear was about 9.6538kN，and the total energy the sample absorbed was 19.3030J; Observing the impact morphology of the sample, the basalt fabricreinforced epoxy resin composite was not perforated, then its failure mode was matrix cracking, drawing and fracture of the fiber. The results provided a scientific basis for basalt fabricreinforced composites, and increase the development of the production related to the basalt fabriccomposites.

The modal properties of carbon fiber woven fabric (with fiber orientation of 45°/-45°) / epoxy resin composites with different fiber volume fraction were studied by using single input and single output free vibration of cantilever beam hammering modal analysis method. The effect of different fiber volume fraction on the modal parameters of laminated composites was analyzed. The experimental results show that with the fiber volume fraction increasing, the natural frequency of laminated composites becomes larger and damping ratio becomes smaller. The fiber volume fraction smaller, the peak value of natural frequency becomes lower and the attenuating degree of acceleration amplitude becomes faster.

Properties Of Composites

The graphene oxide (GO) was obtained by pressurized oxidation method using natural graphite as raw materials. Then the GO/epoxy resin composites were prepared by casting. The mechanical and damping properties of composites were studied. As a result, the impact intensity of GO/epoxy resin composites was prominently improved with the content of the graphene oxide increasing. The glass transition temperature decreased and the damping capacity is improved.

One new kind of epoxy resin toughening agent defined as liquid crystalline polyurethane elastomers (LCPUE) containing mesogenic ester groups and trithylene glycol flexible chain was synthesized and its nematic structure was observed by POM and XRD. The LCPUE was to modify the epoxy resin (E-51). The mechanical properties, fracture surface morphology, and thermal properties of the E-51/LCPUE curing system were systematically investigated. Experimental results revealed that the impact strength of the epoxy resin modified with LCPU is 1.9 times higher than that of the unmodified system, enhanced the thermal decomposition temperature by about 12 °C, and the fracture surfaces all modified systems display tough fracture feature.

Epoxy Resin Composites

The modal properties of carbon fiber woven fabric / epoxy resin composites with different fiber orientation angles were studied by using single input single output free vibration of cantilever beam hammering modal analysis method. With the same fiber volume fraction, the different fiber orientation of the laminated composite has an effect on parameters of vibration mode of composites. The experimental results show that with the fiber orientation increasing, the natural frequency of laminated composites becomes smaller and damping ratio becomes larger. The fiber orientation smaller, the peak value of natural frequency becomes higher and the attenuating degree of acceleration amplitude becomes slower.

Lignin/epoxy resin composites were prepared by blending lignin with epoxy resin cured by polyamide. The effect of the content of lignin and polyamide on the mechanical properties of the lignin/epoxy resin composites was studied systemically. And the structure for the blend of lignin and epoxy resin without the curing agent was characterized by Fourier transform infrared spectroscopy (FTIR). The results of mechanical properties test showed that the bending strength of the composites decreases gradually with increasing the content of lignin, while the impact strength increased firstly and then decreased. The bending strength of lignin/epoxy resin composites showed a trend of increasing firstly and then decreasing with the increase of the content of polyamide, while the impact strength exhibited an opposite trend. The density for the composites increased with the addition of lignin, and polyamide exhibited an inconspicuous effect on density of the composites. The FTIR analysis results showed that the epoxy resin could be cured by lignin without polyamide, which concluded that the lignin could catalyze the cross-linking of epoxy resin or react with epoxy resin, and this bonding effect would beneficial to the properties of lignin/epoxy resin composites.

A indústria automobilística visa desenvolver veículos com melhor desempenho e os materiais compósitos atingem este quesito pois apresentam alta resistência mecânica e baixa densidade. Visando aplicar tal material para a confecção da proteção das polias CVT de um carro BAJA, este trabalho tem como objetivo estudar o comportamento ao impacto dos materiais compósitos, variando a orientação das fibras, em comparação ao aço 1010. Foram conduzidos ensaios de impacto Charpy no material metálico e no compósito nas configurações unidirecionais (0° e 90°), 0°/90°, ±45° e 0°/90°/±45°. Os resultados obtidos mostraram influência dos defeitos gerados no processamento e a absorção de maiores valores de energia decorrente dos mecanismos de liberação de energia dos materiais compósitos. Adicionalmente, foi observado que a configuração ±45° apresentou um melhor desempenho, sendo a melhor opção.The industry is increasingly required to develop vehicles with better performance and composites materials are often the first option due their high mechanic resistance combined with low density. In order to apply this material on CVT protection of BAJA style car, this work main purpose was to study the impact behavior of the carbon fiber and epoxy resin composites, varying the fiber orientation, and compare to the SAE 1010 steel. For that reason, it were performed Charpy impact tests on the steel and on the unidirectional (0° and 90°), 0°/90°, ±45° and mixed (0°/90°±45°) configurations composite material. The results showed that defects inserted during the manufacturing process provided a huge influence on their energy absorbed. It was seen that higher energy absorbed occurred due damage mechanisms release energy. As a conclusion, the ±45° showed the best performance.
